FOLDING AND WRAPPING MACHINE.

Specification of Letters Patent.

Patented Nov. 2c, 1912.

1'0 all whom it may concern:

Be it known that I, SANoFoRn C. Cox, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding and Wrapping Machines, of WhlCh the following is a full, clear, and exact specification.

The invention has more special reference to improvements for stopping the operation of folding and wrapping machines in the event a paper should for any cause fail to be delivered to the final delivery devices or rolls of the machine after it has been partially or substantially folded and wrapped, and it has for its primary object to provide improved agencies'for effectually producing this result.

With a view to the attainment of these ends and the accomplishment of certain other objects which will hereinafter appear, the invention consists in the features of novelty which will now be described with reference to the accompanying drawin and then more particularly pointed out in the claims.

partly broken away, of that portion of a folding and wrapping machine to which these improvements are applied and which will be required for an understanding ofthis invention. Fig. 2 is a detail view of a trigger hereinafter described. Fig. 3 is a perspective view of the same. Fig. 4 is a detail section on the line 4-4:, Fig.1. Fig. 5 is a plan view of the circuit-closers, showing inv dotted lines the relation of the paper clamps or carriers thereto. And Fi 6 is a transverse section on the line 66, %ig. 5.

In the drawings there have been shown only such parts of thefolding machine as are necessary for an understanding of the invention, whose object, as before intimated, is to stop the machine in the event a aper instead of being delivered properly after it is substantially folded and wrapped remains in the paper clamp or other carrier or device provided as a part of the 'WI& ping machine for delivering it'to .the de ivery rolls or-mechanism.

In Fig. l of the drawings on the left is shown a part of a rotating paper clamp or carrier which constitutes the subject-matter of a co-pending application filed May 5,

1906, Serial No. 315,389, and the particular construction and operation of which is not materlal, to the present invention. As shown, however, this carrier consists of a number. of clamps 1, 2, 3, mounted like spider arms on a rotary shaft 4, which as de scribed insaid former application, is given a bodily to and fro motion with respect to the sealing and delivery rolls 5, 6 of the folding machine. It is only necessary to understand, so far as this invention is concerned, that the partially or substantially folded and wrapped paper as shown at 7, Fig. 1, is inserted into these clamps by any suitable mechanism in the folding machine and that the rotating and reciprocatory carrier or clamp moves toward the sealing and delivery rolls 5, 6, which receive the projecting end of the wrapped paper and serve to seal the flap firmly in place, and finally to deliver the paper into the grasp of delivery tapes 8, or in the absence of such tapes, the paper may of course be ejected by the'roll 6 directly. In amachine of this form it sometimes happens that instead of the paper 7 being pulled out of the clamps 1, 2 or 3, it remains therein and continues around with the rotary motion of the carrier and its shaft 4 at the next step or intermittent movement of such carrier. If the machine were not stopped when that omurs some subscriber would be deprived of his paper; and the clamp carrying the remainlng paper would not be able to receive another when it came intoposition for cooperation with the devices of the folding machine which place the papers in these clamps. Therefore, contiguous to the line of rotation of the ends of the clamps 1, 2, 3 are arranged electrical contacts 9, 10, having their ends so curved and separated, as shown in Fig. 1, that they may be closed either by the paper 7 striking the upper one 9 as the paper carrier rotates, or by the paper striking the lower one 10 as the carrier reciprocates toward the sealing rolls 5, these contacts 9, 10, as shown in Fig. 5 ing disposed between the clamps 1 which are arranged at intervals apart on then shaft 4, so as not to be struck by the clamps themselves. By thus closing a circuit through the contacts 9,10, the operationpf the machine is stopped by mechanism Wl'llCh will now be described.

11 is a clutch of any suitable form, de- 110 riving power from a belt 12 or other means,

and this clutch is controlled, that is thrown .into or out of action so as to ope-rate the folding and Wrapping machine and the "shaft & wit-h its carrier clamps 1, 2, 3 and rotating the sealing rolls 5, 6. This engaging and disengaging action of the clutch may be brought about by an ordinary lever 13, which if pulled outwardly or toward the observer as in Fig. 1, or toward the right is in Fig. 4c, throws the clutch out of action and stops the machine and if moved in the opposite direction'will throw the clutch into 7 engaging position. Pivoted to this lever 13 1s a finger 14, which is provided on its under side witha lug 15, arranged to be struck when finger 14 falls, by a trip 16 secured to a shaft 17 which forms a part of the operating mechanism of the machine and which derives its power by any suitable connection such as bevel gears 18, 19 with one member of the clutch 11. The finger 14: while all goes well is supported normally by a trigger 20, having a lug 21, which engages under the end of the finger 14 and holds the lug 15 out ofthe reach of the trip 16. This trigger 20 is controlled by a solenoid 22, whose core 23 is connected by a link 24 to the trigger 20, as clearly shown in Fig. 1, and this solenoid is in circuit by means of wires or conductors 25, 26 with abattery or other source of electricity 27 and the circuit-closeis 9, 10.

Briefly stated, the operation is as follows: The clutch is held in engaging position when the extremity of the arm 14 rests upon the lug 21 of the trigger 20 and as suming the parts to be in this position, the contacts 9 and 10 will be engaged by the paper as it advances should the paper remain in the holder, and when the contacts are brought into engagement the electroresponsive device 20 will be operated to trip the trigger 20 and release the finger 14 so that the lug 15 thereon will stand in thepath of movement of the trip 16 as the shaft 17 rotates. When the trip 16 engages the lug 15, the lever 13 will be shifted to move the clutches out of engaging position to stop the mechanism. 4

In order that the invention might be fully understood by those skilled in the art, the details of an exemplification thereof have been thus specifically described, but

What I claim as new, and desire to secure by Letters Patent, is:

1. In a device for the purpose described, the combination of means for holding a plaper, means for receiving the paper'thereom, electrical contacts arranged to be engaged and closed by the paper while the tacts for automatically throwing the machine out of operation when the contacts are closed.

v. 2. In a device for the purpose described, the. combination of a movable carrier for holding a folded paper, means for receiving the paper from said carrier, and means arranged in the line of movement of the paper while the latter is in the carrier and adapted to be directly engaged by the paper while the carrier is moving for automatically throwing the machine out of operation in the event the paper remains in the carrier after thetime in which it should have passed to the receiving means.

3; "In a device for the purpose described, the combination of a rotating carrier for containing a folded paper, means for extracting the paper therefrom, means for throwin themachine out of operation, and electrica contacts controlling the last said means arranged to be struck by a paper in the carrier should the extracting means fail to extract it.

at. In a device for the purpose described, the combination of a rotating carrier for containing a folded paper, means for extracting the paper therefrom, a clutch which when in engagement operates the folding mechanism, a power driven trip operatively connected with the clutch, a finger having means adapted to be engaged by said trip when released, a trigger for holding said finger out of engagement, and electrical means foractuating said trigger containing contacts, arranged to be struck by the paper in the carrier in the event the extracting means fails to extract it.

5. In a device for the purpose described,

the combination of a paper clamp capable SANDFORD C. COX. Witn .TJoHr'I HUNEKE, -J. Tominson.
